Abstract
A system and method for completing a well with multiple zones of production includes a casing having a plurality of flapper valves integrated therein for isolating each well zone and a perforating gun string for selectively perforating the casing and underlying formation at each well zone to establish communication between the formation and the interior of the casing and to facilitate delivery of treatment fluid to each of the multiple well zones. The system and method may include mechanisms for selectively actuating each flapper valve, such as by detonating a perforating gun in a perforating gun string. The system and method may include providing a perforating gun string having multiple guns, each gun selectively detonated at a corresponding well zone, and the gun string being stored in a lubricator at the surface between alternating sequences of perforating and treating the well zones.
